Hi,

I am currently getting the error:

[ERROR] [1531729856.715593296]: Error connecting to Hokuyo: Could not open serial Hokuyo:
/dev/ttyACM0 @ 115200
could not open serial device.

Initially, after encountering this problem, I was able to resolve it by adding myself to the dialout list as suggested: https://answers.ros.org/question/2866... I was able to view the data from the Hokuyo after doing this.

I am now trying to access the Hokuyo from a different machine. On the drone (where the Hokuyo is connected), I changed ROS_MASTER_URI and ROS_IP to match the PC. On the PC, I then ran:

$ roscore
$ ssh drone-user@drone-IP

I am able to run '$ rostopic list' correctly. However, after typing '$ rosrun urg_node urg_node', I receive the error mentioned above.

Any help is greatly appreciated.

Thanks,

Justin

Not sure if this will help but it turned out my issue was a timing issue, with the drone's clock being reset to Feb 2016

I have managed to fix the error, it was caused by a large discrepancy in time between the PC and the drone. Connecting
